proximity switch
.
Multisensor
System of multiple
USi
to monitor larger surface areas. The
USi
are intersynchro-
nised by the signal
SYNC
. A multisensor system consists of one
master
and up to
24
slaves
.
Noise interference
General side-effect of ultrasound sensor systems. Ultrasonic waves are not au-
dible to humans. The transmission burst of the ultrasonic transducer, however, is
perceived as a clearly audible crackle. At a typical frequency of 20 Hz, this may be
perceived as annoying in the long term. Animals may occasionally also hear the ul-
trasonic waves and be annoyed by them.
Normally open contact
Output
with NO contact function, which effects the
fl
ow of the load current when the
measurement object
is detected and causes the load current to stop
fl
owing when
the
measurement
object
is not detected. (cf.
Output digital
,
OUT
)
Object
Element, which is detected by the ultrasonic proximity switch in the detection
fi
eld.
(cf.
Secondary object
)
Opening angle
Total angle around the
reference axis
of an
ultrasonic proximity switch
, where the
sound level is reduced by 3
dB. [IEC
60947-5-2, 2.3.1.4] (cf.
Reference axis
)
Operating mode 1 Range
USi
operating mode, where the switch point
1 is identical with the
minimum switch-
ing distance
. The detection
fi
eld extends from 1
Range from
minimum switching
distance
on to switch point
2.
Operating mode 2 Ranges
USi
operating mode, where the
detection
fi
eld
is divided into 2
ranges.
Range
1: The sensor-proximal
detection
fi
eld
extends from the
minimum switching
distance
to switch point
1.
Range
2: The sensor-distant
detection
fi
eld
extends from switch point
1 to switch
point
2.
Operating mode Window
USi
operating mode, where Range
1 is not visible. A (monitoring) window is thereby
created between switch point
1 and switch point
2. The operating mode Window
can only be selected with the
parameter assignment software
(optional).
Range
1: The hidden
detection
fi
eld
extends from the
minimum switching distance
to switch point
1.
Range
2: The detection window extends from switch point
1 to switch point
2.
OUT
Abbreviation for output. The USi has 2 outputs per sensor. For sensor 1, these are
OUT 1.1 and OUT 1.2, for sensor 2 OUT 2.1 and OUT 2.2. For USi-IP, OUT 1.1 is
an analog current output with DC 4 to 20 mA. For USi-UP, OUT 1.1 is an analog
voltage output with DC 0 to 10 V. (cf. Output)
Output
Connection on which the output signal of a
proximity switch
is connected. The
USi-PP has 4 digital outputs, 2 each for every
sensor
(Sensor
1, Sensor
2).
USi-IP and USi-UP each have 3 digital outputs and one analog output (
cf. Output
analog, output digital, OUT
)
Output analog
Output on which a linear current characteristic (USi-IP) or a linear voltage (USi-UP)
